The U.S.A. Olympic Synchronized Swimming Team is designing a routine for their upcoming competition. From the center of the pool
Mama L [17]

Answer:

The equation of the circle is;

(x - 2)² + (y - 4)² = 5²  

Step-by-step explanation:

We note that the general equation of a circle is given as follows;

(x - h)² + (y - k)² = r²

Where;

(h, k) = The coordinates of the center of the circle

r = The radius of the circle

The given parameters are;

The location of the center of the pool to the center of their formation = 2 feet to the right and 4 feet up from the center of the pool

The point through which the circle which they form goes through = A point 3 feet to the left and 4 feet up from the center of their formation

Taking the center of the pool as the origin of the coordinate plane system, we have;

The coordinate of the center of the circle = The coordinate of their motion from the center of the circle

∴ The coordinate of the center of the circle = (2, 4)

∴ (h, k) = (2, 4)

h = 2, k = 4

The coordinate of the point through which the circle passes = (2 - 3, 4 + 4) = (-1, 8)

∴ The length of the radius, 'r', can be found as, r = √((-3)² + 4²) = 5 or r = √((-1 - 2)² + (8 - 4)²) = 5

r = 5

The equation of the circle is therefore presented by substituting the values of 'h', 'k', and 'r', as follows;

(x - 2)² + (y - 4)² = 5².

 A movie theater sends out a coupon for 85​% off the price of a ticket. Write an equation for the​ situation, where y is the pri
ra1l [238]

Answer:

y=0.15x

Step-by-step explanation:

Given:

Original price of the ticket is x

Price after using the coupon is y

Coupon discount is 85% of x=0.85x

Therefore, the price after applying coupon is given as the difference of the original price and the coupon discount. That is,

y=x-0.85x=x(1-0.85)=0.15x\\\therefore y=0.15x

The graph is shown below. The graph passes through the origin as the above relationship is a proportional relationship.

The line y=0.15x strictly remains in the first quadrant as both x and y can't be negative as they represent price of tickets and price can never have negative values. Hence, only the first quadrant has both the values of x and y positive.
